Cover Feature: Open‐ and Closed‐Loop Recycling of Polyesters and Post‐Consumer Waste Under Industrially Relevant Conditions Using Bisguanidine Organocatalysts (ChemSusChem 2/2026)
Abstract
The Cover Feature illustrates the bisguanidine organocatalyst-driven recycling of common polyesters, polylactide (PLA), polyethylene terephthalate (PET), and polycaprolactone (PCL). Three catalysts were evaluated in their ability to depolymerize PLA, with the most active demonstrating remarkable versatility and robustness in cascade recycling of polymer mixes and the valorization of post-consumer PET waste, thus highlighting a sustainable pathway toward a circular plastics economy. More information can be found in the Research Article by S. Herres-Pawlis and co-workers (DOI: 10.1002/cssc.202502062).
